Probable Type 2 Autoimmune Pancreatitis: A Case Report and Clinical Management

Abstract

Autoimmune pancreatitis ( AIP) is a rare type of chronic pancreatitis characterized by immune-mediated inflammation of the pancreas.It is often misdiagnosed due to non-specific symptoms such as abdominal pain, congestion , jaundice and radiographic findings that mimic pancreatic malignancy.Without appropriate treatment ,AIP can lead to  endocrine and exocrine pancreatic insufficiency,biliary complications , and irreversible fibrosis(1).In this article,we aimed to increase awareness of the clinical approach to IgG4 –unrelated autoimmune pancreatitis that mimics pancreatic malignancy.
